We studied the effects of cryofocusing on the resolution of volatile components in solid-phase microextraction (SPME). Retention times, resolutions and peak areas estimated using cryofocusing were compared to those observed without cryofocusing. The resolution and peak areas with cryofocusing were found to be greater than those obtained without cryofocusing. Hence, SPME cryofocusing is effective in trace analysis of the volatile components in orange juice.
